This invention relates to a. composition of matter for use as a dressing on machinery belts, clutch bands, brake bands and the like, one of the objects being to provide an efliQ I cient preparation of this kind which can be applied readily to the surface of the belt. or the like and will operate efliciently to prevent slipping and re uce wear A further ob ect is toprovide'a prepara- .tion of this kind which can be used on" all kinds, of beltings and remains efficient through long intervals of time.

. A still further object is to provide a composition of matter which will not buildup.

In' preparng this solution one gallon of turpentine or other pine distillate-such as pinesol is 7 added to ounds of moltenrubber at a temperature om .to-' degrees'centiu de. This mixture is briskly stirred and e substanaprodu'ced constitutes morethan merelymel rubber as it remains in a' 1i uld state after it has thoroughly cool whereas rubber will'become somewhat of a 0 plastic mass when it returns normal temditions.

perature provided turpentine has not been added. The viscosity of the product may be varied by increasing or reducing the amount of solvent used. The dextrose is added to the solution after which the liquid styrax is mixed therewith. The rubber constitutes the base of. the composition, gives the preparation its traction power and causes it to form a film over the surface to which it is applied.- The dextrose gives the preparation its penetrating characteristics. so that itwill freely enter the pores of the belt or the like-and keep the structure soft and pliableunder the most severe weather con The liquid styrax (sweet gum) isusedbeca'use of its pleasant odor and because it insures better adherence of the composi-v -Th e composition of matter produced from the ingredients above stated'is applied to the tion to a leather belt than would otherwise be possible. increase the tracg belt of leather-or fabric arm the clutch or brake band and will form a thin film or coating over. the active surface thereof.. This -fil'm sustains the wear and prevents-the belt or the like from slipping upon the surface I engagedthereby The efliciency of the dressmg. remains constant under. all kinds of weather conditions and as long as the dressing lasts upon the belt and. as before stated, the dressing will not form lumps on the belt or band or upon the pulley or the like ened thereby nor will it tend to pull or disintegrate the belt or thelike. While the dressing ,is designed especially for use on 'eflicient-when used on friction clutches be v ried if desired for m e g difierent're- 1 belts machmeryi has been fmmd vs?
